In Union County, South Dakota, the real estate market exhibits a notable concentration of sales activity among its top agents. According to BatchData's Top Agents Report for the trailing 12 months ending July 2026, the top 20% of agents in the county controlled 41.7% of the total sales volume. This metric provides a clear view into the competitive landscape, highlighting how market share is distributed among real estate professionals.

County Overview
Union County, SD, recorded a total real estate sales volume of $14.8M, representing 27 homes sold by all agents during the July 2026 reporting period. This performance positions Union County as a moderately active market within South Dakota, contributing to the broader state and national real estate picture. The concentration of sales volume reveals that a significant portion of the market's activity is managed by a select group of high-performing agents. Specifically, the top 1% of agents in Union County were responsible for 17.0% of the total sales volume, underscoring the impact of a very small elite group. This level of concentration suggests that success in this market often means navigating an environment where established agents hold substantial sway over transactions.
The distribution of homes sold further illustrates this concentration. The agents comprising the top 20% of the market are responsible for a substantial share of transactions, aligning with their dominance in sales volume. This indicates that these top agents are not only handling higher-value properties but also a significant quantity of the total homes sold within the county. For investors considering entry or expansion in Union County, understanding this agent landscape means recognizing potential gatekeepers and key players who influence property flow and pricing. Agents looking to establish themselves in such a market must develop robust strategies to compete effectively against these entrenched leaders.
Local Market Context
Union County's real estate market, with its $14.8M in sales volume, ranks #7 of 49 counties in South Dakota, accounting for 1.1% of the state's total sales volume of $1.4B. While this places Union County among the more active counties, its share of the state total indicates that South Dakota's real estate activity is distributed across multiple regions rather than being heavily centralized in one or two areas. Nationally, the total sales volume for this period reached $734.1B, showcasing the vast scale of the U.S. real estate market.
The concentration of agent market share in Union County provides insights into the competitive environment. A 41.7% share held by the top 20% of agents suggests a market that is moderately concentrated, but not overwhelmingly so when compared to potentially more fragmented or highly monopolized markets elsewhere. This level of concentration can be appealing to real estate investors, as it indicates a degree of market efficiency and agent expertise, while still allowing for competitive entry. Small landlords and everyday owners looking to sell might find that engaging with a top-tier agent could offer advantages in a market where these agents command a significant portion of the sales. Conversely, newer agents or those looking to break into the market may face higher barriers to entry due to the established presence of these dominant players.
Understanding agent concentration helps investors assess market liquidity and the ease of transaction. In a market like Union County, where a defined group of agents handles a substantial volume, the sales process can be more streamlined due to established networks and expertise. This is particularly relevant for those utilizing tools like property search or smart search to identify opportunities, as connecting with influential agents can accelerate deal flow. BatchData's market reports provide critical insights for real estate investing strategies, enabling professionals to make data-driven decisions. The relative influence of top agents in Union County could point to a stable market where established players maintain consistent activity, a characteristic that often appeals to long-term real estate investor strategies.
